The occlusion planes are used for occlusion culling and not the bounding boxes themselves. These just represent the possible area that is occluded by an occlusion plane.
Using a bounding box to calculate occlusion surfaces may seem fine, but what happens when models, such as donuts, have holes in them ? The bounding box will still encompas the entire object, including the hole, which will cause the occlusion culling to not render items seen through the hole of the donut.
Normally everything is rendered, even if you can't see it. With occlusion culling it only renders the things you can see, so you get better performance. (I also found this after Notch tweeted about occlusion culling)
@AquarianPython Basically, if you can't see something in the game - it won't be rendered. Thus your computer doesn't have to process it at that point in time meaning performance from said game.
For example, if you are in your mine-shaft, you can't see the surface of the map and your housing etc., so why waste resources processing it? You'll likely gain an FPS boost as a result.
@AquarianPython The reason you'll need a semi-decent GPU is that your PC has to calculate what is and isn't in view to determine what to process and what to not. So faster computers utilising OC perform even FASTER, whilst slower computers are still slow and won't benefit from this.
@Bal0rCIM hehe - basically it doesn't render stuff till you get close enough to see it.. for example if you are in a building it will not render outside till you look out a window or go out the door.. technically making the game run faster..

@tingyuyan12 It's basically texture streaming but it hides everything you are not looking at instead of just the textures

Translation: Occlusion culling is just rendering what would be visible, instead of having everything behind what you see and stuff.

Ain't that music from The Elder Scrolls 4: Oblivion (some theme at night i think)?
BTT: Very cool technique. Great idea and great explanation!

The piece is called Peace of Akatosh. I don't know the filename it has when you look through the game files.
